Man, Robin really pisses me off in this arc. It almost made me forget about bitchy Ussop and his Merry dilemma breakdown. They had her out of harms way and out of the blue she clutches sokeking only to return to the damn CP9 guys. Fuck is that about. You were free!!! Believe in Luffy like everyone else dammit!!! She should've known a long time ago that there's no way in hell that they are not going to go after her. Just accept the damn help.
